The Alliance is the largest body serving evangelical Christians in the UK. In its formative years the Alliance particularly stood for the victims of religious persecution and enabled evangelicals from different denominations to work together. As part of a movement 'uniting to change society' the Alliance promotes unity and truth, acting as an evangelical voice to the state, society and the wider church. It works collaboratively with Alliance members and other evangelicals, to proclaim Christ as good news for spiritual and social transformation.

Cross Street Baptist Church is part of the the London Baptist Association of nearly 300 member churches across greater London. The aim of the Association is summed up in their motto: "Making disciples, sharing the good news of Jesus"
